Box-EAsTENER'.

Specification of Letters Patent. Patented J 1111 30, 1914.

Application filed December 7, 1910. serial No. 596,086.

To all whom t may concern Be it known that I, ROBERT FRANK SCHMIDT, of New Market, Province .of-Ontario, Canada, have invented certain new and useful Improvements in Box-Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to fasteners and to boxes and it has for its object to provide a simple, light, cheap and convenient form of fastener for use in connecting to gether sheets of Wood, paper, cardboard or,V similar material but more particularly such material as is used in the construction of storage or shipping boxes or packages, the improvements being of such a nature as to be particularly useful in the manufacture oi folding or knock-down boxes.

To these and other ends the invention consists of certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a perspective fragmentary view of a box constructed in accordance with my invention, the wall portions thereof in connection with which the fastener is used being shown as they appear just before being folded to their proper positions; Fig. 2 is a similar View of the box completely set up with the fasteners in place; Fig. 3 is a section taken substantially on the line 3-3 of F ig. 2 showing one of the fasteners in elevation, and Fig. 4 is a perspective view illustrating the manner in which the fastener is applied to the box.

Similar reference numerals throughout the several figures indicate the same parts.

The device illustrated in the present embodiment of the invention shows the useful application of my improvements to a box such as is usually made of cardboard or heavy paper to constitute the outer casing or container of a letter le and as such it comprises a top wall 1, side walls 2 and a bottom wall 3, the present terminology thereof being suggested merely by the position of the box in the figures. These walls may be rigidly or foldably connected together according to the nature of the box.

To the side Walls 2 are foldably connected, in the present instance, as by scoring extensions of the material thereof at .4, reinforcing flaps 5 which fold beneath a wall mem-l ber 6 hingedly attached to the bottom 3 at the score 7, as shown in Fig. 3. Hinged to the top wall 1 by ascore 8 or otherwise is an outer wall member or flap 9 which folds down against the inner wall member 6 and in this way the end wall ofthe present box is formed.

The inner wall member 6 has at its edgea slot or perforation 10 in the region of the score 7 and of the adjacent corner of the box when formed which the said score defines, while the outer wall member or hinged flap 9l is provided with a perforation 11 arranged in substantially the same vertical plane but out of alinement with the perforation 10 when the members are in superposed or overlapped positions.

The fastener that I employ is preferably composed of a strip 12 of thin pliable sheet metal or any other suitable material which may be readily bent but will hold to its bent shape with considerable persistency. One end 13 of the strip' is doubled into a spaced parallel relationship with the body portion but the other end 141- extends outwardly therefrom while the fastener retains its original formation, as shown in full lines in Fig. 4 and in dotted lines in Fig. 3.

To apply the fastener, the end 13 is inserted in the aperture 10 when the flaps 5 and the wall member 6 have 4been folded down, as shown in Fig. t, until it occupies the position shown in dotted lines in the ligure in which it embraces the edge of the wall member. The end 13 then lies against the inner face of the latter to retain the fas-v tener and the body portion flat against the outer face thereof. The outer wall member 9 is then folded down over the outwardly projecting end 14k of the fastener which end is'passed through the perforation 11 and then clenched down against the outer face of said member to secure it, preferably in a direction which doubles it back upon the body portion whereat a rigid Wallis formed and the box is complete.

I have herein shown two fasteners employed but any number can be utilized according to the size of the parts and the strain imposed.

It will be noted that while the securing .tilt

n'ieinber has a clenched position on both sides oit' the wall or or' the members that it holds together, the elenching operation is necessitated only upon one and that the outer and U accessible side. rlhis permits the whole operation to be readily done by hand rather than by automatic machinery.

I further contemplate use of the fastener in various ways on boxes Wherever two substantially parallel or adjoining and overlapping members are employed. The blank :tor the fastener has no peculiar shape that requires a special die for its formation. @n the other hand it can be produced in quantities by simply cutting oli' sections of a ribbon of metal.

l claini as my invention.

4The conibinationvwith av boX having an inner wali member and an outer Wall niember hinged at opposite edges of one side of the box to i'old toward each other, the free edge of the outer member extending adjacent to the hinge of the inner member' and moine@ being provided With a perforation, and the inner member being provided With a slot alined with its inner face coincident with its hinge-line and opening on the corner of the box at the junction with a side Wall, of a fastener comprising a pliable, flat metal strip having a doubled portion embracing the inner wall and adapted to be applied While in doubled condition by the insertion of the lfree end of one of the parts forming the doubled portion through the slot With a straight movement in. the plane of the under face of the inner Wall, and a securing portion extending outwardly from the outer part of the doubled portieri and through the perforation in the outer Wall, said portion being clenched against the outer face of the latter by bending in a` direction toward the hinge of the inner Wall.
